The James Webb Space Telescope Instruments

The science instruments are the heart of the James Webb Space Telescope. The four science instruments will be contained within the Integrated Science Instrument Module or ISIM. This unit will house the four main instruments that will detect light from distant stars and galaxies, and planets orbiting other stars. The structure (pictured left) is like a chassis in a car providing support for the engine and other components.
